CritVal1 Contains the lower critical value of the experimental
variable associated with the negative
TestScore
value
which was calculated from the input
α
-level.
CritVal2 Contains the upper critical value of the experimental
variable associated with the positive
TestScore
value
which was calculated from the input
α
-level.
DF Contains the degrees of freedom for the t-tests.
Prob Contains the probability associated with the
TestScore
value.
Result For hypothesis tests, contains 0 or 1 to indicate rejection
or failure to reject the null hypothesis.
TestScore Contains the Z- or t-distribution value calculated from the
hypothesis test or confidence interval inputs.
TestValue Contains the value of the experimental variable
associated with the
TestScore
.
App Functions
App functions are used by several of the HP Apps to
perform common calculations. For example, in the
Function app, the Plot view FCN menu has a function
called
SLOPE
that calculates the slope of a given function
at a given point. The
SLOPE
function can be used, from
the Home view or a program, etc. to give the same results
as if you were in the Function app Plot view. App
functions can be used to get the same results in a program
or the Home view or anywhere else- just as if you were in
the app. The App functions described in this section are
grouped by app.
Function app
functions
The Function app functions provide the same functionality
found in the Function app's Plot view under the FCN
menu. All of these operations work on functions. The
functions may be expressions in
X
or the names of the
Function app variable F0 through F9.
AREA Area under a curve or between curves. Finds the signed
area under a function or between two functions. Finds the
area under the function Fn or below Fn and above the
function Fm, from lower
X
-value to upper
X
-value.
